For optimal engine performance and to support emissions regulations compliance, diesel engine’s blow-by should contain minimal oil aerosol before directing it to the atmosphere (open) or routing to the engine air intake air system (closed).
Unwanted and unavoidable blow-by gases prove problematic in the engine crankcase. Equipment difficulties can be avoided by properly venting blow-by gases. Subsequently, diesel engine environmental standards are growing stricter internationally, prompting consumers to seek more environment friendly products.
Fleetguard’s series of crankcase ventilation (CV) solutions safeguard crankcase ventilation systems for your emissions-certified engines. It does not compromise engine performance or the environment with oil mist and drips. The CV product line offers the industry’s highest blow-by oil mist separation efficiency in a cost-effective and versatile package. Fleetguard offers both Open Crankcase Ventilation (OCV) & Closed Crankcase Ventilation (CCV) solutions.

The Crankcase Ventilation System Operation: – The air pressure (crankcase gasses) builds up inside diesel engines. This air must be released from the engine. This process is called Positive Crankcase Ventilation (PCV). Oil droplets and aerosol oil contaminants that are sub-micron or undetectable to the human eye can be entrained in the air as it exits the engine as an oil mist. Additionally, there may be combustion byproducts in the crankcase ventilation gases that would increase the amount of particulate matter (PM) released into the atmosphere.
